Method for Calibrating Cameras with Non-Overlapping Views |
| 摘要 |
A method calibrates one or more cameras, wherein the one or more cameras acquire images of a scene for different viewpoints, and wherein the images are non-overlapping, by first constructing a 3D model of the scene using a calibration camera that is independent of the one or more cameras, and a. simultaneous localization and mapping (SLAM) procedure. 2D-to-3D correspondences between each of the images and the 3D model are determined. Then, calibration parameters of each of the one or more cameras are estimated using a 2D-to-3D registration procedure. |

1. A method for calibrating one or more cameras, wherein the one or more cameras acquire images of a scene for different viewpoints, and wherein the images are non-overlapping, comprising the steps of:
constructing a 3D model of the scene using a calibration camera that is independent of the one or more cameras, and a simultaneous localization and mapping (SLAM) procedure; determining 2D-to-3D correspondences between each of the images and the 3D model; and estimating calibration parameters of each of the one or more cameras using a to 2D-to-3D registration procedure, wherein the steps are performed in a processor. |
